Can I get XML output instead of JSON output?
We currently do not provide XML output format. There exist many ready-to-use third-party libraries/packages to convert JSON format to XML format, e.g. Python packages dicttoxml and json2xml. They will be essentially the same packages we would use if decide to provide XML output format. For this reason and also for reducing the development complexity, we decided not to provide XML format.
What's behind MyChem.info?
MyChem.info is built on ElasticSearch, a document-based database and powerful query engine. Unlike more commonly used relational database systems (e.g., Oracle, MySQL), data are stored as "key-document" pairs. The "document" is a JSON-formatted chemical annotation object, while the "key" is a gene ID (Entrez or Ensembl). The hierarchical structure of chemical annotation data can be represented naturally in this key-document model. This simple object structure in ElasticSearch greatly simplified both data loading and data queries, and also gains impressive query performance and flexibility.
